Mr Hendry was the first MP to ask a question during international development questions.

He questioned International Development Secretary Justine Greening about her department's preparations for the UN world humanitarian summit.

But Mr Bercow spotted Mr Hendry was no longer in his place in the chamber minutes later as MPs continued to discuss the issue.

Mr Bercow told MPs: "Where is Mr Hendry? The fella has just asked a question and he's beetled out of the chamber.

"We've still got exchanges on that question. I know he's a new member but he must learn.

"A member must not ask a question and then leave. There are continuing exchanges upon that matter and I'm sure the honourable gentleman is at least as interested in the opinions of others as he is in his own opinions.
